Dedicated in 1972, the park contains 86,416 acres with elevations ranging from 3,650 to 8,749 feet at the summit of Guadalupe Peak, the highest point in Texas. The park has four of the state's highest peaks, deep canyons, and a rare mixture of plant and animal life. Access to the park's rugged interior is by hiking and backpack camping along 80 miles of marked trails.
